In view of this, in the eleventh embodiment, as shown in FIG. 18, the identification code unique to the CD-ROM and the input standby state data for screen output in the input standby state are stored in the RAM 8, and at the same time when the power is turned on, at S1 This input waiting state data is read from the RAM 8 and the character input waiting state to be searched in S2 is set.
Then, while the input is accepted in S7, the CPU 5
In 3 to S6, the identification code and the initial setting data are read from the RAM 8. For this reason, since the reading of the initial setting data is completed while the user is inputting the character to be searched, it can be apparent that the system is started at the same time when the power is turned on.

However, in the eleventh embodiment, when the identification code is read, if it is not the predetermined information stored in the RAM 8, the input standby state is immediately released in S8, and the system is started up similarly to the conventional example. I do.

Although the RAM 8 is used in the eleventh embodiment, a mask ROM 9 as shown in the third embodiment may be used.

In the eleventh embodiment, the input standby state of characters to be searched is displayed at the same time when the power is turned on.
As shown in the flowchart of FIG. 19, the identification code read from the CD-ROM may be displayed after the information of the same type is confirmed in S2.

In the eleventh embodiment, the input standby state data RAM 8 for screen output in the input standby state is stored. However, a plurality of identification codes and input standby state data are stored, and at the same time when the power is turned on, the CD- The identification code may be read from the ROM, the input standby state data corresponding to the identification code may be read from the RAM 8, and the screen for the search character input standby state may be displayed.
