[0057]
3 and 4 show an example in which a sorter 80 is connected as a peripheral device.
[0058]
As shown in the configuration diagram of FIG. 3, the sorter 80 connected in place of the paper discharge table 70 is configured such that a plurality of paper receiving tables 82 arranged vertically are moved up and down by a drive mechanism 86 (see FIG. 4). It has become.

[0060]
The performance information of the sorter 80 includes information on the paper size that can be received by the sorter 80, information on a print speed that can be handled, and the like.
[0061]
The stencil printing apparatus 10 executes an operation range setting program before executing a print control program for controlling printing, reads performance information of each mounted mechanism unit and connected peripheral device, and determines an operation range. Set. The print control program performs control so that the printing operation is performed within the operation range set by the operation range setting program.
[0062]
The flowcharts of FIGS. 5 and 6 show the procedure of the operating range setting program.
[0063]
The CPU 2 reads the performance information of each mechanism unit 20, 50, 60, 70 mounted on the apparatus main body 12 and the connected peripheral device 80 via the data communication unit 9 (# 10). When the reading is completed (YES in # 12), the parameters of the printing control program are set so as to set the cutting size of the base paper according to the opening size of the plate cylinder 62 based on the performance information of the printing drum unit 60. (# 14). That is, the base paper is set so as to cover the opening portion of the plate cylinder 62.
[0064]
Next, the maximum speed (hereinafter referred to as “print drum maximum speed”) Vd that can be handled by the printing drum unit 60 and the maximum speed that can be handled by the sheet feed unit 50 (hereinafter “sheet feed unit maximum speed”). Compared with Vf (# 16). When the printing drum maximum speed Vd is greater than or equal to the sheet feed table maximum speed Vf (YES in # 16), the maximum value of the setting range of the printing speed (hereinafter referred to as “set maximum speed”) Vp is supplied. The paper base portion maximum speed Vf is set (# 18). If the printing drum maximum speed Vd is smaller than the sheet feed table maximum speed Vf (NO in # 16), the set maximum speed Vp is set to the printing drum maximum speed Vd (# 20).
[0065]
Next, based on the performance information of the paper feed tray unit 50, it is determined whether or not the paper feed stand unit 50 can detect the paper size (# 22). If it can be detected (YES in # 22), the maximum value of the paper size that can be handled by the paper feed tray unit 50 (hereinafter referred to as “the maximum paper size of the paper feed tray unit”) Lf and the paper discharge tray unit 70 The maximum paper size that can be handled (hereinafter referred to as “the maximum paper size of the paper discharge tray”) Lr is compared (# 24). When the maximum paper size Lf of the paper feed tray portion is larger than the maximum paper size Lr of the paper discharge tray portion (YES in # 24), the maximum paper size Lmax that can be set in the paper feed tray portion 50 is set to the maximum value of the paper discharge tray portion. The print control program parameters are set so as to limit to the paper size Lr (# 26). When the maximum paper size Lf of the paper feed table portion is smaller than or equal to the maximum paper size Lr of the paper discharge table portion (NO in # 24), the print control program normally has the paper feed table as a control parameter of the paper feed table portion 50. Since the maximum sheet size Lf is used, step # 26 is skipped.
[0066]
If the paper feed tray unit 50 cannot detect the paper size (NO in # 22), the above steps # 24 and # 26 are skipped.
[0067]
Next, it is determined whether or not the sorter 80 is connected to the apparatus main body 12 (# 28).
[0068]
When the sorter 80 is connected (YES in # 28), the maximum speed (hereinafter referred to as "sorter maximum speed") Vs that the sorter 80 can handle is compared with the set maximum speed Vp (# 30). If the sorter maximum speed Vs is greater than or equal to the set maximum speed Vp (YES in # 30), the set maximum speed Vp is maintained as it is, and the operation range setting program is terminated. If the sorter maximum speed Vs is smaller than the set maximum speed Vp (NO in # 30), the set maximum speed Vp is changed to the sorter maximum speed Vs, and the operation range setting program is terminated.
[0069]
If the sorter 80 is not connected (NO in # 28), it is determined whether or not the corresponding paper size Lr of the paper discharge tray 70 is fixed to a specific size (for example, postcard size) (# 34). When the paper size Lr of the paper discharge tray 70 is fixed to a specific size (YES in # 34), the paper size that can be set by the paper feed tray 50 is fixed to the paper size Lr of the specific size. In this manner, the print control program parameters are set (# 36), and the operation range setting program is terminated. If the paper size Lr of the paper discharge platform 70 is not fixed to a specific size (NO in # 34), step # 36 is skipped, and the operation range setting program is terminated.
[0070]
The setting of the operating range is not limited to the above embodiment, and can be performed in various modes.
[0071]
For example, the operating range of the image reading apparatus 20 may be limited based on the print-compatible dimensions of the opening portion of the plate cylinder 62. Alternatively, the size of the paper that can be fed by the paper feed table 50 may be limited based on the printing-compatible dimensions of the opening portion of the plate cylinder 62.
[0072]
However, if the entire operation range of the print control program is set based on the performance information of each mechanism unit, there is an operation range with no margin depending on the operation of the apparatus, which may cause inconvenience in operation. Therefore, it is desirable to select the performance information and set the operating range.
[0073]
When further restricting the operating range, or when mounting or connecting a mechanism unit or peripheral device of a type in which performance information is not recorded, the performance information can be input from the operation panel 8 of the apparatus main body 12. In this case, the CPU 2 adds the performance information input from the operation panel 8 and sets the operation range.
[0074]
Next, a second embodiment will be described with reference to FIGS. The second embodiment is generally configured in the same manner as the first embodiment and operates in the same manner. Below, it demonstrates centering around difference.
[0075]

A certain reversing unit 160 is detachably mounted.
[0076]
The paper feed stand unit 140 conveys the paper 146 placed on the paper feed stand 142 from the top by the paper feed roller 144 one by one. The feed roller 112 in the apparatus main body 110 rotates at an appropriate timing in synchronization with the driving of the adjacent first stencil printing unit 150 to feed the paper to the first stencil printing unit 150.
[0077]
The paper discharge table 180 is disposed adjacent to the paper discharge unit including the paper discharge belt 114 and the fan unit 116 in the apparatus main body 110, and includes a paper receiving table 182, a stopper 186, and a pair of guides 184.
[0078]
The image reading unit 120 reads a document image and generates image data. The image data may be received from an external computer.
[0079]
The plate making and discharging apparatus 130 is an apparatus in which a plate making plate 138 for making roll-shaped base paper 138 and mounting it on the porous substrates 152 and 172 and a plate removing portion for removing the base paper from the porous substrates 152 and 172 are integrated. is there. Based on the image data generated by the image reading unit 120, the plate-making plate feeding unit makes a base paper 138 with the thermal head 132, cuts it to a predetermined length with the cutter 134, and the perforated substrates 152 of the stencil printing units 150 and 170. , 172. The plate discharging unit removes the base paper mounted on the porous substrates 152 and 172 of the stencil printing units 150 and 170, draws the paper into the inside by a drawing roller 136, and winds up as a plate discharging roll 138. For example, as described in Japanese Patent Publication No. 7-17083, the plate making and discharging apparatus 130 detaches the base paper from the porous substrates 152 and 172 of the two stencil printing units 150 and 170. Move together horizontally (left and right in the figure). Since the stencil feeding and discharging apparatus 130 is commonly used for the plurality of stencil printing units 150 and 170, the entire stencil printing apparatus 100 can be reduced in size.
[0080]
In the stencil printing units 150 and 170, the porous substrates 152 and 172 are arranged on the upper side of the paper conveyance path, and the press rollers 156 and 176 are arranged on the lower side. The porous substrates 152 and 172 are endless belts that circulate between the sprockets 153, 154, 173, and 174 disposed above and below, and ink is applied to the inner surfaces of the porous substrates 152 and 172 inside the lower curved portion. Ink rollers 155 and 175 are arranged. The perforated substrates 152 and 172 are formed with openings (ink transmitting portions) having a predetermined size and are covered with a base paper. Press rollers 156 and 176 are arranged below the porous substrates 152 and 172, move at an appropriate timing in a direction in contact with and away from the porous substrates 152 and 172, and press the paper toward the porous substrates 152 and 172. On the downstream side in the paper conveyance direction, peeling claws 158 and 178 are disposed adjacent to the porous substrates 152 and 172 so that printed paper is peeled from the porous substrates 152 and 172.
[0081]
Since the stencil printing units 150 and 170 use the perforated substrates 152 and 172 that circulate in an oval shape, it is possible to reduce the size in the paper conveyance direction as compared with the case where a cylindrical plate cylinder is used. Thereby, the printing apparatus 100 can be reduced in size in the paper conveyance direction.
[0082]
The reversing unit 160 is configured to be compatible with the stencil printing units 150 and 170 with respect to attachment to and detachment from the apparatus main body 110. The reversing unit 160 includes a guide block 168 and a reversing guide plate 166 that form a substantially Y-shaped paper conveyance space, a receiving roller 162, a reversing guide roller 163, a feeding roller 164, and a feed roller 165. Is provided. The sheet on which the upper surface is printed by the stencil printing unit 150 is conveyed upward by the receiving roller 162 and the reverse roller 163, and is conveyed between the reverse guide plates 166. When the trailing edge of the paper passes over the guide block 168, the reverse roller 163 rotates in the reverse direction, and the paper is conveyed downward. The guide block 168 faces the downstream side of the paper conveyance direction, that is, the other stencil printing unit 170 side. Is changed, and the sheet is conveyed by the feed roller 164 with the front and back sides reversed. The feed roller 165 rotates at a predetermined timing in conjunction with the operation of the stencil printing unit 170, like the feed roller 112 of the apparatus main body 110.
[0083]
By disposing the reversing unit 160 between the two stencil printing units 150 and 170, double-sided printing can be performed.
[0084]
FIG. 8 is a block diagram of a control system of the stencil printing apparatus 100.
[0085]
The CPU 102 that controls the control includes a ROM 104 that stores data such as programs, a RAM 106 that temporarily stores data, an operation panel 108, an image reading unit 120, stencil printing units 150 and 170, a plate making and plate feeding device 130, A reversing unit 160, a paper feed stand unit 140, a paper discharge stand unit 180, and a data communication unit 109 are connected.
[0086]
The image reading unit 120, the stencil printing units 150 and 170, the reversing unit 160, the paper feed table unit 140, and the paper discharge table unit 180 are provided with data communication units 120x, 150x, 170x, 160x, 140x, and 180x, respectively. The data communication unit 109 is connected.
[0087]
The data communication units 120x, 150x, 170x, 160x, 140x, and 180x include a ROM (not shown) that stores performance information of each mechanism unit, and a transmission circuit for transmitting the performance information to the data communication unit 109. Including. The data communication unit 109 is an interface circuit between the data communication units 120x, 150x, 170x, 160x, 140x, 180x and the CPU 102. Similarly, the operation panel 108 and the plate making and discharging apparatus 130 may be provided with a data communication unit.
[0088]
The performance information is information regarding what can be a limiting condition for the operating range of the stencil printing apparatus 10 among the performance of each mechanism unit.
[0089]
The performance information of the reversing unit 160 includes information regarding a compatible paper size, information regarding a compatible printing speed, and the like.
[0090]
Next, an operation range setting program for reading the performance information and setting the operation range before executing the print control program will be described with reference to the flowcharts of FIGS. 9 and 10.
[0091]
The CPU 102 reads the performance information of each mechanism unit (# 50), and when the reading is completed (YES in # 52), based on the performance information of each stencil printing unit 150, 170, the perforated substrates 152, 172 are opened. The printing control program parameters are set so as to set the cutting size of the base paper in accordance with the size of the portion (# 54), that is, the cut base paper is set so as to cover the opening portion.
[0092]
Next, the maximum speed (hereinafter referred to as “first maximum speed”) Vd1 that can be handled by the first stencil printing unit 150 and the maximum speed that can be handled by the second stencil printing unit 170 (hereinafter referred to as “second maximum speed”). ) Vd2 is compared (# 56). If the first maximum speed Vd1 is greater than or equal to the second maximum speed Vd2 (YES in # 56), the maximum value of the print speed setting range (hereinafter referred to as “set maximum speed”) Vp is set to the second maximum speed Vd2. (# 58). If the first maximum speed Vd1 is smaller than the second maximum speed Vd2 (NO in # 56), the set maximum speed Vp is set to the first maximum speed Vd1 (# 59).
[0093]
Next, the set maximum speed Vp is compared with the maximum speed (hereinafter referred to as “maximum reverse speed”) Vr that can be handled by the reverse unit 160 (# 60). If the set maximum speed Vp is greater than or equal to the maximum reverse speed Vr (YES in # 60), the set maximum speed Vp is changed to the maximum reverse speed Vr (# 62). If the set maximum speed Vp is smaller than the maximum reverse Vr (NO in # 60), the above step # 62 is skipped and the set maximum speed Vp is not changed.
[0094]
Next, the set maximum speed Vp is compared with a maximum speed (hereinafter, referred to as “sheet feed section maximum speed”) Vf that can be handled by the sheet feed section 140 (# 64). If the set maximum speed Vp is greater than or equal to the sheet feed table maximum speed Vf (YES in # 64), the set maximum speed Vp is changed to the maximum sheet feed speed Vf (# 66). When the set maximum speed Vp is smaller than the paper feed table maximum speed Vf (NO in # 64), the above step # 66 is skipped and the set maximum speed Vp is not changed.
[0095]
Next, it is determined whether or not the paper feed unit 140 can detect the paper size (# 68).
[0096]
If it can be detected (YES in # 68), the maximum value of the paper size that can be handled by the paper feed table 140 (hereinafter referred to as “the maximum paper size of the paper feed table”) Lf and the paper discharge table 180 The maximum paper size that can be handled (hereinafter referred to as “maximum paper size of the paper discharge tray”) Lr is compared (# 70). When the maximum paper size Lf of the paper feed tray portion is larger than the maximum paper size Lr of the paper discharge tray portion (YES in # 70), the maximum paper size Lmax used in the paper feed tray portion 140 is changed to the maximum paper size Lr of the paper discharge tray portion. The parameters for the print control program are set so as to be limited (# 72). When the maximum paper size Lf of the paper feed table portion is smaller than or equal to the maximum paper size Lr of the paper discharge table portion (NO in # 70), the print control program normally has the paper feed table as a control parameter of the paper feed table portion 140. Since the maximum sheet size Lf is used, step # 72 is skipped.
[0097]
If the paper feed stand section 140 cannot detect the paper size (NO in # 68), the above steps # 70 and # 72 are skipped.
[0098]
Next, it is determined whether or not a sorter is connected to the apparatus main body 110 (# 74).
[0099]
When the sorter is connected (YES in # 74), the maximum speed (hereinafter referred to as "sorter maximum speed") Vs that the sorter can handle is compared with the set maximum speed Vp (# 76). If the sorter maximum speed Vs is greater than or equal to the set maximum speed Vp (YES in # 76), the set maximum speed Vp is maintained as it is, and the operation range setting program is terminated. If the sorter maximum speed Vs is smaller than the set maximum speed Vp (NO in # 76), the set maximum speed Vp is changed to the sorter maximum speed Vs (# 78), and the operation range setting program is terminated.
[0100]
If the sorter is not connected (NO in # 74), it is determined whether or not the corresponding paper size Lr of the paper discharge tray 180 is fixed to a specific size (for example, postcard size) (# 80). When the paper size Lr of the paper discharge tray 180 is fixed to a specific size (YES in # 80), the paper size that can be set on the paper feed tray 140 is fixed to the paper size Lr of the specific size. In this way, the print control program parameters are set (# 82), and the operation range setting program is terminated. If the paper size Lr of the paper discharge platform 180 is not fixed to a specific size (NO in # 80), step # 82 is skipped, and the operation range setting program is terminated.
[0101]
Next, a third embodiment will be described with reference to FIG.
[0102]
The stencil printing apparatus of the third embodiment is configured in substantially the same manner as FIG. 7 of the second embodiment, and a mechanism section such as a stencil printing unit or a reversing unit can be mounted on the unit mounting portion of the apparatus main body. Further, as shown in FIG. 3 of the first embodiment, a peripheral device such as a sorter can be connected.
[0103]
The stencil printing apparatus of the third embodiment performs printing control by resetting the operating range conditions set by the operating range setting program when the mounted mechanism and the connected peripheral device are not used.
[0104]
That is, as shown in FIG. 11, the CPU reads the use mode setting status of the mounted mechanism unit and the connected peripheral device (# 100).
[0105]
When the reading is completed (YES in # 112), it is determined whether or not all the mounted mechanical units and connected peripheral devices are used (# 114). When all are used (YES in # 114), the operating range condition set by the operating range setting program is maintained (# 116). If not (NO in # 114), the operating range condition is reset based on the use / nonuse condition of the mounted mechanism and the connected peripheral device (# 118).
[0106]
Next, it is determined whether or not the usage environment is a condition that restricts the operating range of the mechanism unit and the peripheral device (# 120).
[0107]
If the condition is to give a constraint (YES in # 120), the temperature, humidity, and paper thickness to be fed are read (# 122). When the reading is completed (YES in # 124), an operation condition setting routine based on the use environment or the like is executed (# 126), and the process ends.
[0108]
If the condition for giving the constraint is not satisfied (NO in # 120), the above steps # 122, # 124, # 126 are skipped and the process is terminated.
[0109]
For example, when the sorter is used, the sorter mode is set by the sorter mode setting button on the operation panel. Therefore, when the sorter mode is not set, the sorter is not used. When the sorter is not used at the start of printing, the CPU performs printing control after resetting the operating range.
[0110]
Also, when single-sided printing using only the first stencil printing unit or single-sided two-color printing using both the first stencil printing unit and the second stencil printing unit without using the reversing unit, the single-sided single-color printing mode (Reversing unit and second stencil printing unit not used) or single-sided two-color printing mode (reversing unit not used) is set. In such a case, the CPU performs print control after resetting the operating range condition on the condition that the mounted mechanism unit is not used.
[0111]
Next, a stencil printing apparatus according to a fourth embodiment will be described with reference to FIG.
[0112]
The stencil printing apparatus of the fourth embodiment reads the detection data of the temperature sensor and the humidity sensor provided in the stencil printing apparatus and the paper thickness detection data of the paper feed, and corrects the conditions of the operating range as necessary.
[0113]
Since the viscosity of the ink increases due to a decrease in temperature and affects the load of the printing speed, a predetermined maximum speed condition for limiting the printing speed when the predetermined temperature is reached is set according to the type of ink. (For example, 100 sheets / min or less, or 80 sheets / min or less).
[0114]
The supply unit of the ink is attached to the printing drum unit or the stencil printing unit, and the type of ink is read as performance information of the printing drum unit or the stencil printing unit, for example. That is, the ink type is read by recognizing the shape of the ink pack or the information attached to the ink pack as the performance information of the printing drum unit or the stencil printing unit.
[0115]
When the temperature is equal to or lower than the predetermined temperature of the used ink (if there are a plurality of printing drums or stencil printing units, one is applicable) and the set maximum speed Vp is higher than the predetermined maximum speed of the used ink. , Rewrite the set maximum speed to the predetermined maximum speed.
[0116]
Also, the sorter generates paper wrinkles or paper jams depending on the paper quality. Therefore, in addition to the mechanical limit conditions, a predetermined maximum speed condition for limiting the printing speed according to the humidity and the paper thickness is set. For example:
80 sheets / min or less at humidity <80% and paper thickness ≦ 80μm
65 sheets / min or less at humidity ≧ 80% and paper thickness ≦ 80μm
[0117]
Information that restricts the printing speed in accordance with the humidity and the paper thickness is registered and read as sorter performance information. The paper thickness is detected by a transmissive sensor provided in the paper feeding unit.
[0118]
When the humidity and the paper thickness of the paper supply satisfy the above conditions and the set maximum speed Vp is larger than the predetermined maximum speed of the sorter based on the conditions, the set maximum speed Vp is replaced with the predetermined maximum speed for correction.
[0119]
Specifically, it operates as shown in the flowchart of FIG.
[0120]
It is determined whether or not the detected temperature is equal to or lower than a predetermined temperature corresponding to the ink to be used (if there is a plurality of printing drum units or stencil printing units, whether or not one is applicable) (# 200). When the temperature is equal to or lower than the predetermined temperature of the used ink (if there are a plurality of printing drum units or stencil printing units, one is applicable) (YES in # 200), the set maximum speed Vp is the predetermined maximum speed of the used ink. It is determined whether it is larger (# 202). If not (NO in # 200), the process proceeds to step # 206.
[0121]
When the set maximum speed Vp is larger than the predetermined maximum speed of the ink used (YES in # 202), the set maximum speed Vp is rewritten and corrected to the predetermined maximum speed (# 204). If not (NO in # 202), step # 204 is skipped.
[0122]
Next, it is determined whether or not the sorter mode using the sorter is set and the operation range of the sorter is restricted by humidity and paper thickness (# 206). When the sorter mode is set and the operation range of the sorter is restricted by the humidity and the paper thickness (YES in # 206), it is determined whether the humidity and the paper thickness satisfy the predetermined condition of the sorter ( # 208). If not (NO in # 206), the following steps are skipped and the process ends.
[0123]
If the humidity and paper thickness satisfy the predetermined conditions (YES in # 208), it is determined whether the set maximum speed Vp is greater than the predetermined maximum speed of the sorter (# 210). If not (NO in # 208), the following steps are skipped and the process ends.
[0124]
If the set maximum speed Vp is larger than the predetermined maximum speed of the sorter (YES in # 210), the set maximum speed Vp is rewritten with the predetermined maximum speed of the sorter (# 212), and the process is terminated. If not (NO in # 210), the process skips step # 212 and ends.
[0125]

[0132]
In addition, according to Steps # 22 to # 26 (see FIG. 6), in Example 1, the maximum paper size Lmax that can be set in the paper feed unit is not limited by the performance of the paper discharge unit, but in Example 2, Limited to postcard size (A6).
[0133]
Also, in steps # 28 to # 36 (see FIG. 6), in Example 1, the paper size of the paper feed table is not fixed, but in Example 2, it is fixed only to the postcard size (A6).
