2. Description of the Related Art Speech synthesis alarms are appropriately installed in, for example, automatic machinery, robots, production lines, parking lots, and the like.
Signals such as parts shortage, danger display, alert, etc. are notified by voice, and are used for maintaining the safety of users such as workers and for maintenance of automatic machinery and the like.

[0003] The voice synthesis alarm has a built-in ROM that stores voice messages. Since the ROM is usually mounted on the board, the user of the voice synthesizing annunciator may be required to replace the ROM storing a certain voice message with the ROM of another voice message in addition to the aging of the ROM.
A need arises for attaching and detaching the board on which the OM is mounted to and from the speech synthesis alarm.

[0004] First, there has conventionally been a method of disassembling the box itself of the speech synthesis alarm and attaching and detaching the ROM board to and from the speech synthesis alarm.

However, in this method, it is necessary to disassemble the box itself of the speech synthesis alarm, so it takes time to attach and detach the ROM board, and the box of the speech synthesis alarm is easily damaged. In addition, this method has the inconvenience that the voice synthesis alarm must be removed from the installation site of the automatic mechanical device or the like depending on the installation location of the voice synthesis alarm.

Therefore, the first conventional example shown in FIG.
A configuration is adopted in which a ROM box 62 in which M is incorporated is inserted into an opening 63 provided in a box body of the voice synthesis alarm 61, and is assembled to a female connector 64 provided on a wall at the bottom of the opening 63. With this configuration, the ROM can be replaced by removing the ROM box 62 from the opening 63 and further removing the ROM board from the ROM box 62.

A second conventional example shown in FIG.
73 is mounted on a ROM board 74, the ROM board 74 is fixed to a lid 75 with screws or the like, and the lid 75 is
The male connector 78 provided on one end of the ROM board 74 is inserted into a female connector provided at the back of the opening 72 in the voice synthesis alarm 71. Combine. As a method of fixing the lid 75 to the box of the voice synthesis alarm 71, screws 76, 77

To replace the ROM 73, remove the screws 76, 77, pull the handle 753 provided on one surface of the lid 75 with a finger, remove the male connector 78 from the female connector, and remove the lid 75 from the opening 72. Drawer, ROM board 7
By removing the cover 4 from the cover 75, the ROM 73 can be replaced.

[Problems to be solved by the invention]

[0008] However, the first conventional example is a ROM.
The disadvantage is that the cost is high because the box 62 is required as a separate part. Further, in the first conventional example, the ROM cannot be replaced unless the ROM board is removed from the ROM box 62, so that it is troublesome. next,
In the second conventional example, the ROM board 74 must be fixed to the lid 75 with screws or the like.
Since the voice synthesizing alarm 71 must be fixed to the box of the voice synthesizing alarm 71, separate parts such as screws are required, and there is a disadvantage that the number of assembling steps of the voice synthesizing alarm 71 increases. And
In both the first conventional example and the second conventional example, the ROM box 6
2 and the lid 75 will be pulled out by hand. In this case,
If the male connector is difficult to remove from the female connector,
There is a problem that the male connector and the female connector are easily bent and damaged because it is difficult to pull straight out. Furthermore, in both the first conventional example and the second conventional example, since the ROM box 62 and the lid 75 are pulled out by hand, if the male connector and the female connector are strongly fitted, the male connector and the female connector will not come off. Sometimes. Therefore, the user often does not strongly fit the male connector and the female connector. However, if the male connector and the female connector are not strongly fitted, the connection between the ROM board and the voice synthesizing annunciator tends to be insufficient, and the reliability is low. Had a shortcoming.
