The address of the comment table 14A provided in the memory 14 is specified. As shown in FIG. 3, comments regarding programs to be processed in the future and their execution dates are written in advance in this comment table 14A. Therefore, the date data and comment data written in the comment table 14A are read out from separate output lines _L1 and _L2 , respectively, and the date data read out from the output line _L1 is read out from the B register 24 and the comment data written in the comment table 14A. AND circuit 25
The comment data input to the output line _L2 and read from the output line L2 is input to the AND circuit 25b.
The date data temporarily stored in the B register 24 is sent to a comparison circuit 26. Further, date and time data sent from the clock circuit 15 is applied to the comparison circuit 26 via the A register 27.
The comparison circuit 26 will be described in detail later, but the B register 24
The date data held in the A register 27 is compared with the current date and time data held in the A register 27, and if they match, the data is sent to the AND circuit 25 via the output line 26a.
A match signal is output to a and 25b. AND circuit 2
5a and 25b open their gates in response to the coincidence signal, and send the date and time data and comment data from the comment table 14A to the display controller 28. This display controller 28 stores the input date and time data and comment data in an internal refresh memory, and also stores the input date and time data and comment data in the CRT display device 13.

FIG. 4 is a circuit configuration diagram showing details of the comparison circuit 26. In the figure, 261 is an AND circuit to which the date data held in the A register 27 is applied, and 262 is an AND circuit to which the date data held in the B register 24 is applied. The AND circuits 261 and 262 are gate-controlled by a comparison command IC from a control section (not shown), and their output signals are input to input terminals a and b of a subtraction circuit 263, respectively. The subtraction circuit 263 subtracts the data applied to the input terminal b from the data applied to the input terminal a, and produces an output signal d.
Computation result data is output from output terminal c, and a carry signal is output from output terminal c.

The signals output from the output terminals d and c of the subtraction circuit 263 are input to the set terminal S of the flip-flop 265 via the NOR circuit 264. The output signal of flip-flop 265 is input as a coincidence signal to AND circuits 25a to 25c in FIG. 2 via output line 26a. The flip-flop 265 is reset by a write completion signal WE from the display controller 28 given from a control section (not shown). Further, the output of the NOR circuit 264 is given to one input terminal of an AND circuit 267 via an inverter 266,
The comparison command IC is inputted to the other input terminal of the AND circuit 267 via a delay circuit 268.
The delay time of this delay circuit 268 is equal to the delay time of the subtraction circuit 268.
The calculation time is set longer than the calculation time of 3. Then, the output signal of the AND circuit 267 and the write completion signal WE are passed through the OR circuit 269 to the output line 2.
6b and sent to the address controller 23 as an increment signal. The comparison circuit 26 configured as described above inputs the date data held in the A register 27 and the date data from the comment table 14A held in the B register 24 to the AND circuit 261 when the comparison command IC is given. , 262 to the subtraction circuit 263. This starts a subtraction operation, and if the contents of the A register 27 and the B register 24 do not match, a "1" signal is output from at least one of the output terminals d and c of the subtraction circuit 263, and the NOR circuit 2
The output of 64 becomes "0". Therefore, the output of the inverter 266 becomes "1", and the AND circuit 267
An increment signal is outputted to the output line 26b via the OR circuit 269. Furthermore, when the contents of the A register 27 and the B register 24 match, the signals output from the output terminals d and c of the subtraction circuit 263 are both "0", and the output of the NOR circuit 264 is "1". ” and the flip-flop 265 is set. As a result, a "1" signal, that is, a match signal, is output from the flip-flop 265, and the AND circuit 2
5a to 25c. Then, when the writing to the display controller 28 is finished and a write completion signal WE is sent from the control section, the flip-flop 265 is reset and the write completion signal WE is outputted via the OR circuit 269 as an increment signal. Output line 26b
is sent to the address controller 23.
