Further, the plurality of engaging claws 165 are sequentially (or almost simultaneously) pressed from the upper surface side of the top panel 16 so that the respective engaging claws 165 are fitted into the corresponding engaging concave portions 117.

As described above, the slide switch 122, the eject button 131 and the reset button 141 are mounted on the upper housing 11a without being screwed. Therefore, the number of parts is small, assembly is easy, and the number of assembling steps can be reduced. Therefore, the above embodiment is suitable for mass production and can be manufactured at low cost. For repair, the top panel 11 can be easily removed by removing the upper housing 11a from the lower housing 11b and pushing the engaging claws 165 inward from the lower surface of the upper housing 11a.

Next, the operation of each part after the above-described video game machine 10 is assembled will be described.

When using the video game machine 10, the user inserts the cartridge 20 in which the program data of the desired game content is stored into the cartridge insertion hole 111 of the video game machine 10. As a result, the connection terminal 23 formed on the cartridge substrate 22 in the cartridge 20 and the connector 191 of the video game machine 10 are electrically connected. Then, the user slides the slide switch 122 and turns on the power switch 121 to start the game. At this time, the lock plate 17 rotates in conjunction with the sliding movement of the slide switch 122. As a result, the protrusion 171 of the lock plate 17 fits into the lock groove 21 formed in the cartridge 20. As a result, the cartridge 20 is locked so as not to come off. Therefore, even if the eject button 131 is undesirably pressed while the power switch 121 is turned on, the cartridge 20 cannot be removed or prevented. Further, when the power is turned on without inserting the cartridge 20, the protrusion 171 of the lock plate 17 hits the door member 15, so that the door member 15 is locked and the insertion of the cartridge 20 is impossible or prevented. As shown in FIG. 2 or 4, if the pressing protrusion 131a of the eject button 131 is formed in an arc shape, there is an advantage that the contact state between the pressing protrusion 131a and the pressing portion 132a of the eject lever 132 can be made smooth. is there.

Next, in order to further clarify the features of the above-described embodiment, the operation when the cartridge 20 is removed from the video game machine 10 will be described in comparison with the related art.

The cartridge locking mechanism disclosed in Japanese Utility Model Laid-Open No. 2-49595 is such that when the user pulls up the side surface of the cartridge in which the notch is not formed, the cartridge is centered on the claw of the arm member. There is a drawback that the cartridge rotates and as a result, the cartridge comes off and the claws are damaged. On the other hand, in the above embodiment, since the lock plate 17 is widely inserted in the horizontal direction in the substantially central portion of the one main surface of the cartridge 20, even if the cartridge 20 is pulled up at an angle, the cartridge 20 is not removed. It is not pulled out from 0, and the protrusion 171 is not damaged.

When the lock mechanism disclosed in Japanese Utility Model Publication No. 2-49595 is applied to a video game machine having an eject mechanism (for example, a product name “Family Computer” sold by the applicant of the present application), Even if the eject mechanism is operated with a small force, a very large force is applied to the arm member and / or the claw part, so the force applied in the direction of ejecting the cartridge concentrates on the claw part and the notch part, resulting in damage to the claw part. There is it. On the other hand, in the locking mechanism in the above-described embodiment, an elongated locking groove 21 extending horizontally on one main surface of the cartridge 20 and a protrusion 171 inserted over almost the entire area of the locking groove 21. Composed. Therefore, the area of the portion that receives the force applied in the direction of extracting the cartridge 20 is larger than that of the conventional lock mechanism. Moreover, since the lock plate 17 penetrates the hole 111b (see FIG. 4) formed in the upper housing 11a and is inserted into the locking groove 21, the inner wall of the hole 111b of the upper housing 11a is perpendicular to the lock plate 17. Regulate the movement of Therefore, even if a large force is applied to the cartridge 20 by the eject mechanism 13, the force is decomposed into each member and the lock plate 17 is not damaged.
