A transparent touch panel 9 is disposed close to the front side of the image display unit 8. The periphery of the touch panel is covered with a mask body 10, and the mask body 10 is attached to a horizontally long metal upper cover 11 that also serves as speaker covers arranged on the left and right sides of the image display unit 8 according to the width of the face 5. It is stuck.

FIG. 2 shows a cross-sectional view of the video game machine. FIG. 3 shows an enlarged view of the round circle portion of FIG. FIG. 4 shows a front view of the touch panel placed on the frame.
A power supply circuit 14 and an electronic circuit 15 for operating the video game machine are built in the standing portion 2.
An image display unit 8 is attached to the upper frame 12 and the lower frame 13 that are horizontally provided on the upper and lower sides in front of the head 5. The touch panel 9 leans against the upper frame 12 and the lower frame 13 in close proximity to the display surface 8 a of the image display unit 8. The upper frame 12 and the lower frame 13 have receiving surfaces 12a and 13b that receive the back side of the touch panel in parallel and close to the display surface 8a of the image marking unit, and the receiving surfaces 12a and 13a include the touch panel 9. The holding pieces 12b and 13b are erected in accordance with the lower edges of the four corners, and the holding pieces 12c and 13c are erected on the left and right sides of each frame in accordance with the side edges of the four corners of the touch panel.

The display surface 8a of the image display unit is tilted upward by about 85 degrees, and the touch panel 9 has an angle of inclination of the receiving surface 13a of the lower frame of 85 degrees, and is erected on the receiving surface 13a of the lower frame 13. Most of the load is applied to the holding piece 13b that receives the lower edge of the touch panel, and the touch panel 9 is supported. The upper edge of the touch panel 9 is placed against the receiving surface 12a of the upper frame. The left and right positions of the touch panel 9 are positioned by the frame holding pieces 12c and 13c, respectively, and touch detection corresponding to the display position of the image display unit can be performed.
The touch panel 9 is an ultrasonic type, and the reflective arrays 9a to 9d are arranged on the glass surface of the glass substrate surface of 46 cm in length, 60 cm in width, and 0.5 cm in thickness along the vicinity of the sides on a transparent glass plate that matches the rectangle of the display screen. Is provided.

FIG. 5 shows a principle diagram of an ultrasonic touch panel. FIG. 4A shows a surface acoustic wave on the surface of the touch panel, and shows a state where the position B is touched. FIG. 4B shows a transmission signal and a reception signal in the X direction.
An X transmitter Xs and an X receiver Xr are provided on the surface of the touch panel in the vicinity of the right edge of each of the upper and lower reflection arrays 9a and 9b. A Y transmitter Ys and a Y receiver Yr are provided on the surface of the touch panel in the vicinity of the upper edge of each of the reflection arrays 9c and 9c on the right side and the left side. As a result, the ultrasonic waves transmitted from each transmitter to each reflection array emit surface acoustic waves uniformly on the touch panel surface by each reflection array, enter the reception-side reflection array, enter the receiver, and signals received by each receiver. The position B where the touch panel surface is touched can be specified based on the time when the signal is weakened.

  Here, a cable C for transmitting / receiving signals to / from the X transmitter, X receiver, Y transmitter, and Y receiver is connected to a touch panel from a sensing circuit (not shown), and this cable C receives and transmits ultrasonic waves. It is wrinkled on the outer surface of the touch panel so as not to get in the way. For this reason, when fixing the touch panel 9 to a frame, it is necessary to avoid and fix the cable C.

Returning to FIG. 4, the cable enters the right side along the edge of the surface from the lower right side of the touch panel, and is connected to the X transmitter, and further, the right edge of the touch panel is connected to the up X receiver and the Y receiver. Is connected to the Y receiver on the left side along the upper edge.
Therefore, it is desirable to fix the touch panel to the frame while avoiding the right and upper edges of the cable.

The mask body 10 is attached by opening the open / close door 6 to the front, fixing the speaker cover portion to the housing with screws 10, and screwing the lower side to a bracket 13 d provided on the lower frame 13. Thereby, the mask body 10 contacts the surface of the touch panel 9 via the ribs 10a and 10b. Thereby, the opening part of a mask body is located on the reflective array of a touchscreen, and has the clearance gap g between touchscreens over the perimeter.
Therefore, by providing the gap g between the opening of the mask body and the touch pen surface, the surface acoustic wave generated from the reflective array is not obstructed, and the reflective array of the touch panel may be shaken during the transportation of the housing. This prevents the reflective array from being slid in contact with the opening of the mask.

Since the holding pieces at the four corners of the touch panel in the first embodiment need only hold the touch panel 9, it is sufficient that the lower edge of the touch panel can be held as a minimum. If only the lower edge of the touch panel 9 can be held, the receiving surface 12a of the frame is inclined upward. Therefore, by receiving the holding piece 13b on the lower edge of the touch panel, the back surface of the touch panel 9 becomes the receiving surface 12a of the upper frame. Can be supported. In this case, in addition to the legs that abut the touch panel surface, the cover body secures the touch panel by providing legs that are addressed to the left and right edges and the upper edge of the touch panel from the cover body side to secure the touch panel. can do.

FIG. 7 shows another embodiment of a holding piece for receiving the lower edge of the touch panel, and corresponds to an enlarged view in a circle of FIG.
Furthermore, the holding piece 13a that receives the lower edge of the touch panel of the lower frame 13 has at least a portion where the thickness t of the touch panel is perpendicular to the touch panel surface, and the portion exceeding the thickness of the touch panel 9 is inclined slightly upward. After removing the cover body, when the touch panel 9 is separated from the image display surface 8a, the lower edge of the touch panel is tilted toward the near side with the holding piece 13b at the lower edge as an axis by tilting the upper edge of the touch panel toward the near side. At this time, it can be easily separated from the image display surface 8a without being detached from the holding piece 13b. This is convenient because the user touches the back side of the touch panel 9 and the image display surface 8a without detaching the touch panel at the time of cleaning when the back surface or the image display surface of the touch panel becomes dirty.
