[Prior Art] A paper tape reader reads data from a paper tape on which data has been recorded by punching holes in units of 5 to 8 units, according to preset recording specifications, that is, NUL (empty), data start code, end code, and data length. The data is read while checking the format, such as the presence or absence of flower characters. FIG. 5 shows an example of the format of the paper tape 1a. The flower characters are characters with holes punched in them so that the tape number can be identified as shown in the figure. This format is set with different specifications depending on the user, and is set using an approximately 8-bit setting terminal. Alternatively, specifications fixed by the user are set in the ROM.

[0004] The reasons for setting the format are: (1) errors in punched data, intervening dust, or reading errors due to abnormal loads due to external forces such as twisting of the paper tape 1a or tentacles, (2) differences in formats due to differences in users, and However, this is because there are differences in the recording format of the paper tape 1a due to differences in the data length of the paper tape 1a depending on the purpose, and it is necessary to check this.

[0005]

[Problems to be Solved by the Invention] According to the above conventional method, the format of the paper tape is set using a setting terminal of about 8 bits, but the setting is troublesome and the amount of information that can be set is limited. However, there are problems in that the format check accuracy during reading is poor, and although it is possible to set a plurality of formats in the ROM setting method, the settings are fixed and difficult to change after shipment.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tape reader that can increase the number of recording specifications to be set and improve the accuracy of specification checking, since recording specifications can be set by reading a tape medium. It is said that

[Embodiment] An embodiment of the present invention will be explained with reference to FIGS. 2 to 4. The same reference numerals indicate the same objects throughout the figures.

Paper tape 1a in FIG. 2, reading section 2a, recognition section 3a, setting data memory 4a, and checking section 5a
The format setting instruction button 60a corresponds to the tape medium 1, reading means 2, recognition means 3, storage means 4, checking means 5, and setting instruction means 60 in FIG. 1, respectively.

In the block diagram of FIG. 2, a paper tape reader 11a has a plurality of paper tapes 1a of different formats,
reading section 2a, recognition section 3a, setting data memory 4a, checking section 5a, keyboard (hereinafter referred to as KB) 6,
It is composed of a liquid crystal display (hereinafter referred to as LCD) 7, a transmitting/receiving section 8, an interface section 9, and a control section 10,
The interface unit 9 connects to a host computer (hereinafter referred to as host) 12, and the host 12 has another paper tape reader 1 having the same functions as the paper tape reader 11a.
1b and 11c are connected.

In addition to a power switch and a reading start button, the KB 6 also includes a format setting instruction button 60a, a reading speed instruction button 61 (corresponding to the speed instruction means of claim 2), and an automatic transfer instruction button (transmission of claim 3). (corresponding to the instruction means) 62
It is equipped with operation buttons such as.

The format setting instruction button 60a instructs a setting mode for setting the format of the data recorded on the paper tape 1a, such as NUL, start code, end code, presence or absence of flower characters, and data length.

The reading speed designation buttons 61 are a plurality of buttons for selecting and designating the reading speed according to the length of the paper tape 1a when the setting mode is designated, and the speed designation is added to the format to be set. Under normal conditions, a fast speed corresponding to the short paper tape 1a is set.

As a result, when reading the paper tape 1a after the setting mode is canceled, reading is started at a high speed, and when reading exceeds a predetermined data length, reading is performed at a specified slow speed. That is, if the length of the paper tape 1a is long, reading failures are likely to occur due to phenomena such as entanglement, so the reading speed is slowed down, and if the length of the paper tape 1a is short, there is no risk of failure, so the reading speed is increased.

The automatic transfer instruction button 62 instructs an automatic transfer mode for transmitting the reading speed and format stored in each storage area of the setting data memory 4a to the host 12. The reading unit 2a reads data using a combination of holes in the paper tape 1a.

The recognition unit 3a includes a NUL/data discrimination unit 30
and a counter 31 for counting the data length (number of digits)
The reading unit 2a recognizes the format read from the paper tape 1a.

The setting data memory 4a is a non-volatile memory that has a plurality of storage areas and stores the formats of the plurality of paper tapes 1a to be set in each storage area, and even if the power of the paper tape reader 1a is turned off, It is composed of SRAM, EEPROM, etc. supported by batteries.

The checking section 5a determines the format of the data read from the paper tape 1a by the reading section 2a according to the format set in the setting data memory 4a.
, the presence or absence of flower characters, the start code and end code, check the end of the data, parity check, and data length check.

The control unit 10 includes a CPU and a control program, and the CPU controls each unit by the control program, and when a setting mode is designated by the format setting instruction button 60a, recognizes the data read from the paper tape 1a. The setting data is stored in the setting data memory 4a, and the paper tape 1a is read at a specified speed according to an instruction from the reading speed designation button 61, and the specified speed is added to the setting data. After the setting mode is released, the data on the paper tape 1a is read at a specified speed, the format is checked by the checking unit 5a, and the data is sent to the host 12 or printed out to a printer (not shown). Also, when automatic transfer mode is set, the setting data in the setting data memory 4a is transferred to the host 1.
Send to 2.

Since it has such a structure and function, the operation will be explained next with reference to the flowcharts of FIGS. 3 and 4. 1) Setting the format (Figure 3) ■ First, press the format setting instruction button 60a of the KB6 to set it to the setting mode, and insert the paper tape 1a for setting into the paper tape reader 11a.

[0023]Next, the start code is confirmed and set, the reading speed designation button 61 is pressed to designate the reading speed, and the reading start button is pressed to start reading by the reading section 2a. The reading speed is stored, for example, in storage area #1 of the setting data memory 4a.

■ Presence or absence of data in the block before the starting code,
That is, the presence or absence of NUL and flower characters is determined and recognized by the NUL/data discrimination section 30 of the recognition section 3a. If there is no flower character, the flow of ■ is performed.

■If there is a flower character, the flower character data, parity specification (even number, odd number, none) as a flower character specification.
and the data length are determined and counted by the NUL/data determining section 30 and the counter 31, and are stored in the #1 storage area of the setting data memory 4a.

■ Set the data parity specifications (even, odd, none), data length, and number of data units (5 to 8) using the last data before continuous NUL data as the end code. Store in storage area.

■If there is another paper tape 1a to be formatted, repeat the flow from ■ to ■ to sequentially set #2, #
3. When all settings are completed, press the format setting instruction button 60a again to cancel the setting mode.

[0028]Next, the automatic transfer instruction button 62 is pressed to transmit the setting data in the setting data memory 4a to the host 12 in automatic transfer mode. The host 12 immediately sends the setting data to the paper tape readers 11b and 11c, and the paper tape readers 11b and 11c store their respective setting data memories 4a.
to be memorized.

(2) When the transmission to the host 12 is completed, the automatic transfer instruction button 62 is pressed again to cancel the automatic transfer mode. 2) Reading and checking paper tape 1a (Figure 4) ■
First, paper tape 1a is set on paper tape leader 11a.

(2) When the reading start button is pressed, reading by the reading section 2a is started. ■From the first read data, search the corresponding area and read it in the format depending on the reading speed of each setting data in the storage areas #1, #2, - of the setting data memory 4a and the presence or absence of data in the block before the start code. .

[0031] While the paper tape 1a is being read at the reading speed, a parity check (if an even number or an odd number has been determined) or skipping is performed for the flower character part depending on the read format.

■ Check the data from start to finish based on the determined "start code and end code". ■Parity check of data part (if even or odd numbers are confirmed)
I do. ■Check the data length for short, long, and errors.

In this way, by using the paper tapes 1a on which data are recorded in different formats to perform format settings, not only is the setting operation easy, but also the setting terminals of about 8 units as described in the conventional example can be used. Compared to the method of setting a limited number of files step by step, the format can be set more accurately and the accuracy of checking can be significantly improved. Further, unlike the conventional method, there is no need to provide a ROM with a format set, and it is possible to respond flexibly to user requests.

Furthermore, when setting the format, the paper tape 1a
The reading speed can be set according to the length of the paper tape 1a, and reading failures due to twisting of the paper tape 1a can be prevented and stable reading can be achieved.

Furthermore, it is not necessary for the other paper tape readers 11b and 11c connected to the host 12 to read the paper tape 1a anew and set the format, which saves time and effort.
