The printer 10 includes a recording head 20 that selectively ejects a plurality of recording wires, and a carriage 30 on which the recording head 20 is mounted, and includes characters by striking the recording wires ejected from the recording head 20 onto a sheet. This is a dot impact printer for recording images. As the sheet, a cut sheet (including postcards and copy paper), a continuous sheet (including copy paper), and the like are used.
[0028]
As shown in FIG. 1, the printer 10 roughly includes a printer main body 12 that constitutes a recording unit, a tractor unit 13, and a sheet guide 14, which are covered with an exterior cover 11.
[0029]
The printer main body 12 includes a recording mechanism unit 22 including a recording head 20 and a carriage 30, and a sheet conveying mechanism unit 26 including a platen 23 and sheet conveying rollers 24 and 25.
[0030]
As shown in FIGS. 1 and 2, the printer main body 12 has a sheet guide frame 28, a platen 23, a carriage guide shaft 29, and roller shafts 24a and 25a substantially parallel between the left side frame 27L and the right side frame 27R. It is constructed across. The right side frame 27R further supports a sheet conveyance motor 32 and a carriage drive motor 31, and the sheet conveyance motor 32 rotates the platen 23 and the roller shafts 24a and 25a via a gear train mechanism (not shown). . The platen 23 and the roller shafts 24a and 25a rotate to convey the sheet along the sheet guide 14 and the sheet guide frame 28.
[0031]
The carriage guide shaft 29 supports the carriage 30 so as to be movable in the axial direction. The carriage 30 is fixed to a carriage drive belt, and the carriage drive belt is driven by a carriage drive motor 31 to reciprocate (reciprocate) in the axial direction of the carriage guide shaft 29.
[0032]
The recording head 20 is mounted on the carriage 30 and reciprocates in the main scanning direction (arrow X direction) as shown in FIG. 2 when the carriage 30 reciprocates in the axial direction of the carriage guide shaft 29. The recording head 20 has a configuration in which a plurality of recording wires are ejected toward the platen 23.
[0033]
As shown in FIG. 1, a ribbon take-up shaft 50 is attached to the printer main body 12, and the ribbon take-up shaft 50 is connected to a ribbon drive unit 90 driven by a motor (not shown). A ribbon cartridge (not shown) is detachably attached to the ribbon take-up shaft 50, and the ink ribbon of the ribbon cartridge is disposed between the recording head 20 and the platen 23. As a result, the recording head 20 projects the recording wire and strikes the ink ribbon while moving in the main scanning direction by the carriage 30, and the recording head 20 corresponds to the sheet conveyed between the platen 23 and the recording head 20. Record images such as text.
[0034]
The tractor unit 13 conveys the sheet toward the sheet guide frame 28 by the rotation of the tractor belt 13A. Here, the exterior cover 11 includes a cover 15 that can be opened and closed on the front side of the printer 10, and the sheet can be set on the tractor unit 13 by opening the cover 15.
[0035]
The sheet guide 14 functions as a manual feed tray when manually feeding sheets, and when the sheet is fed from the front of the printer 10 by the tractor unit 13 (in the case of front feeding), the sheet guide 14 Functions as a paper output tray.
[0036]
Under the above-described configuration, the recording operation by the recording head 20 is performed for one line by firing a recording wire from the recording head 20 while the recording head 20 is moved in the main scanning direction (arrow X direction) by the carriage 30. Each time one line is recorded, the tractor unit 13 and the sheet transport mechanism unit 26 in the case of front sheet feeding, and the platen 23 in the case of rear sheet feeding (manual sheet feeding) Is carried out by transporting a predetermined length (for a normal line) and repeating these operations.
[0037]
The control board 40 (see FIG. 1) controls the recording head 20, the carriage drive motor 31, and the sheet transport motor 32 described above.
[0038]
FIG. 3 is a schematic configuration block diagram of the control board 40.
[0039]
The control board section 40 includes a controller (control means) 70, an interface (I / F) 75, a motor drive section 80, and a recording head drive section 85, when roughly classified.
[0040]
The controller 70 includes a CPU (Central Processing Unit) 71, a ROM (Read Only Memory) 72, a RAM (Random Access Memory) 73, and the like, and centrally controls the operation of the printer 10 according to a program stored in the ROM 72. The ROM (storage means) 72 is a rewritable ROM such as an EEPROM (Electrically Erasable and Programmable ROM) and stores various control programs, data, and the like. The RAM 73 is a memory that temporarily stores programs read by the CPU 71, print data, and the like.
[0041]
The interface 75 transmits / receives various data such as print data to / from an external device such as a personal computer (PC) connected via the communication cable 76 under the control of the controller 70.
[0042]
The motor drive unit 80 drives the carriage drive motor 31 and the sheet conveyance motor 32 under the control of the controller 70.
[0043]
The recording head drive unit 85 drives the recording head 20 under the control of the controller 70 to selectively project the recording wire.
[0044]
By the way, as shown in FIG. 1, the outer cover 11 of the printer 10 is configured such that a cover 11a that covers the upper part of the moving range of the carriage 30 can be opened and closed for replacement and maintenance of the ribbon cartridge and the like. A cover sensor (mechanical switch, optical sensor, electrostatic sensor, etc.) 86 for detecting the open state of the cover sensor 86 is provided, and an output signal of the cover sensor 86 is input to the controller 70.
[0045]
With the above configuration, when the control board unit 40 communicates with an external device such as a personal computer connected via a communication cable and receives print data from the external device, the print data and the output of the cover sensor 86 are output. The recording control is performed based on the state (open state or closed state) of the cover 11a based on the above.
[0046]
Next, the relationship between the cover state and the recording control will be described.
[0047]
FIG. 4 is a processing flowchart in the case of controlling the recording speed after determining the state of the cover.
[0048]
In FIG. 4, it is assumed that the cover is in the closed state in the initial state.
[0049]
First, the controller 70 determines whether or not the cover is open based on the output signal of the cover sensor 86 (step S1).
[0050]
If it is determined in step S1 that the cover remains closed (step S1; No), the controller 70 causes the motor to perform the next printing based on the currently set recording speed (printing speed). Control of normal setting printing for controlling the drive unit 80 and the recording head drive unit 85 is performed (step S4). As a result, the motor driving unit 80 drives the carriage driving motor 31 and the sheet conveying motor 32 in accordance with the currently set recording speed (printing speed). Further, the recording head driving unit 85 inputs the recording wire at a timing synchronized with the recording speed (printing speed) by driving the recording head 20 corresponding to the currently set recording speed (printing speed). Selectively protrudes corresponding to the print data.
[0051]
If it is determined in step S1 that the cover is open (step S1; Yes), the controller 70 ensures the safety of the user when the recording is continued as it is at the currently set recording speed (printing speed). It is determined whether or not it can be secured (step S2).
[0052]
That is, whether or not the next moving speed of the carriage 30 exceeds a predetermined safe speed that can ensure the safety of the user when the carriage 30 and thus the recording head are scanned at the currently set recording speed. Is determined. Here, the predetermined safe speed that can ensure the safety of the user means a speed at which the moving speed of the carriage 30 does not pose a danger to the user even if the user contacts the carriage 30.
[0053]
If it is determined in step S2 that the user's safety cannot be ensured when recording is performed at the currently set recording speed (step S2; No), the controller 70 determines the next carriage 30. Safety setting printing is performed in which the moving speed is set to a speed equal to or lower than the safe speed and recording (printing) is performed (step S3). As a result, the motor drive unit 80 drives the carriage drive motor 31 and the sheet conveyance motor 32 so that the moving speed of the carriage 30 becomes a safe speed, for example. In addition, the recording head drive unit 85 drives the recording head 20 in correspondence with the safe speed, thereby selectively protruding the recording wire in correspondence with the print data at a timing synchronized with the safe speed.
[0054]
If it is determined in step S2 that the user's safety can be ensured even when recording is performed at the currently set recording speed (step S2; Yes), the controller 70 is currently set. Based on the recording speed (printing speed), the normal setting printing is controlled to control the motor driving unit 80 and the recording head driving unit 85 so as to perform the next printing (step S4). As a result, the motor driving unit 80 drives the carriage driving motor 31 and the sheet conveying motor 32 in accordance with the currently set recording speed (printing speed). Further, the recording head driving unit 85 inputs the recording wire at a timing synchronized with the recording speed (printing speed) by driving the recording head 20 corresponding to the currently set recording speed (printing speed). Selectively protrudes corresponding to the print data.
[0055]

[0059]
If it is determined in step S12 that the cover remains closed (step S12; No), the controller 70 performs the next printing based on the currently set recording speed (printing speed). Control of normal setting printing for controlling the drive unit 80 and the recording head drive unit 85 is performed (step S14). As a result, the motor driving unit 80 drives the carriage driving motor 31 and the sheet conveying motor 32 in accordance with the currently set recording speed (printing speed). Further, the recording head driving unit 85 inputs the recording wire at a timing synchronized with the recording speed (printing speed) by driving the recording head 20 corresponding to the currently set recording speed (printing speed). Selectively protrudes corresponding to the print data.
[0060]
If it is determined in step S12 that the cover is in an open state (step S12; Yes), the controller 70 sets the next moving speed of the carriage 30 to a speed lower than the safe speed and performs recording (printing). Safety setting printing is performed (step S13). As a result, the motor drive unit 80 drives the carriage drive motor 31 and the sheet conveyance motor 32 so that the moving speed of the carriage 30 becomes a safe speed, for example. In addition, the recording head drive unit 85 drives the recording head 20 in correspondence with the safe speed, thereby selectively protruding the recording wire in correspondence with the print data at a timing synchronized with the safe speed.
[0061]
If it is determined in step S11 that the user's safety can be ensured even when recording is performed at the currently set recording speed (step S11; Yes), the controller 70 is currently set. Based on the recorded recording speed (printing speed), the normal setting printing is controlled to control the motor driving unit 80 and the recording head driving unit 85 so as to perform the next printing (step S14). As a result, the motor driving unit 80 drives the carriage driving motor 31 and the sheet conveying motor 32 in accordance with the currently set recording speed (printing speed). Further, the recording head driving unit 85 inputs the recording wire at a timing synchronized with the recording speed (printing speed) by driving the recording head 20 corresponding to the currently set recording speed (printing speed). Selectively protrudes corresponding to the print data.

Control of normal setting printing is performed to control the motor driving unit 80 and the recording head driving unit 85 so as to perform the next printing based on the printing speed being recorded (step S24). As a result, the motor driving unit 80 drives the carriage driving motor 31 and the sheet conveying motor 32 in accordance with the currently set recording speed (printing speed). Further, the recording head driving unit 85 inputs the recording wire at a timing synchronized with the recording speed (printing speed) by driving the recording head 20 corresponding to the currently set recording speed (printing speed). Selectively protrudes corresponding to the print data.
[0066]
If it is determined in step S21 that the cover is closed (step S21; No), the controller 70 determines whether the currently set recording speed (printing speed) is the original recording speed (printing speed). It is determined whether or not (step S22). That is, it is determined whether or not the currently set recording speed is set lower than the original recording speed in order to ensure the safety of the user.
[0067]
If it is determined in step S22 that the currently set recording speed is not the originally set recording speed (step S22; No), the controller 70 has originally set the next moving speed of the carriage 30. Speed return printing is performed for recording (printing) by setting the recording speed (step S23). As a result, the motor drive unit 80 drives the carriage drive motor 31 and the sheet transport motor 32 so as to have the originally set movement speed of the carriage 30. Further, the recording head driving unit 85 drives the recording head 20 in accordance with the recording speed that was originally set, thereby selectively protruding the recording wire in correspondence with the print data at a timing synchronized with the safe speed. .
[0068]
If it is determined in step S22 that the currently set recording speed is the same as the originally set recording speed (step S22; Yes), the controller 70 sets the currently set recording speed. Based on (printing speed), control of normal setting printing is performed to control the motor driving unit 80 and the recording head driving unit 85 so as to perform the next printing (step S24). As a result, the motor driving unit 80 drives the carriage driving motor 31 and the sheet conveying motor 32 in accordance with the currently set recording speed (printing speed). Further, the recording head driving unit 85 inputs the recording wire at a timing synchronized with the recording speed (printing speed) by driving the recording head 20 corresponding to the currently set recording speed (printing speed). Selectively protrudes corresponding to the print data.

[0072]
If it is determined in step S31 that the user's safety cannot be ensured when recording is performed at the currently set recording speed (step S31; No), the controller 70 outputs the output of the cover sensor 86. It is determined whether or not the cover is open based on the signal (step S32).
[0073]
If it is determined in step S32 that the cover is closed (step S32; No), the controller 70 sets the next moving speed of the carriage 30 to the originally set recording speed and records (prints). Speed return printing is performed (step S33). As a result, the motor drive unit 80 drives the carriage drive motor 31 and the sheet transport motor 32 so as to have the originally set movement speed of the carriage 30.
