[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image recording apparatus used for a facsimile, a copying machine, or the like.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there are known an image recording apparatus using roll paper capable of recording according to the length of an original, and an image recording apparatus using cut paper for easy paper arrangement. When roll paper is used, it is possible to record according to the length of the document, but there is a problem that the paper is uneven and difficult to organize. In the case of cut paper, it is easy to organize the paper. However, when the original is short, there is a problem that a lot of paper is wasted.
[0003]
[Problems to be solved by the invention]
Conventional image recording apparatuses use either roll paper or cut paper, and the operator can select either roll paper or cut paper as needed. Therefore, there was a problem in the convenience of the image recording apparatus.
[0004]
An object of the present invention is to solve the problems of the above-described conventional image recording apparatus.
[0005]
[Means for Solving the Problems]
In order to achieve the above-described object, the present invention provides an image recording apparatus having one thermal head and capable of selecting either one of a roll paper roll and a cut paper cassette. The roll paper roll is disposed between the feeding-side ink ribbon roll and the feeding-side ink ribbon roll arranged side by side across the platen roller and the thermal head, and the cut-sheet cassette. In addition, a document tray, a document transport member for transporting a document separated from the document tray, a reading sensor for reading the document, and a document discharge port for discharging the document read by the reading sensor are arranged. Second, a cutter member is disposed between the roll paper roll and the thermal head. Each of the conveyance paths for the cut paper and the roll paper to the round head is formed separately.
[0006]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 which is a front view including a partial cross section of the image recording apparatus of the present invention. However, the present invention is not limited to this embodiment unless it exceeds the gist of the present invention. Is not to be done.
[0007]
Reference numeral 1 denotes a cut paper cassette in which a cut paper removably inserted in the casing C is stored. Reference numeral 2 denotes a pickup roller for taking out the cut paper stored in the cut paper cassette 1. is there.
[0008]
Reference numeral 3 denotes a platen roller arranged in parallel with the pickup roller 2 at a predetermined interval. A single thermal head 4 is disposed on the platen roller 3. Reference numerals 5 and 6 denote a feeding-side ink ribbon roll and a winding-side ink ribbon roll that are arranged side by side with the platen roller 3 and the thermal head 4 interposed therebetween. The ink ribbon 7 fed from the feeding-side ink ribbon roll 5 is guided to appropriate guide pins 8 a to 8 c and passes between the platen roller 3 and the thermal head 4 to be wound around the winding-side ink ribbon roll 6. Taken.
[0009]
Reference numeral 9 denotes a cut paper path formed between the pickup roller 2 and the platen roller 3, and reference numeral 10 denotes a pair for conveying the cut paper or roll paper recorded by the thermal head 4 toward the recording paper discharge port 11. The recording paper discharge member is composed of rollers 10a and 10b.
[0010]
Cut sheets stored in the cut sheet cassette 1 are conveyed one by one by the pickup roller 2, inserted between the platen roller 3 and the thermal head 4 through the cut sheet passage 9, and thermally transferred and printed by the ink ribbon 7. After that, the recording paper discharge member 10 is configured to carry out the recording paper discharge port 11.
[0011]
Reference numeral 12 denotes a roll paper roll around which the roll paper 13 is wound, which is disposed between the feeding-side ink ribbon roll 5 and the cut paper cassette 1, and the leading end of the roll paper 13 fed out from the roll paper roll 12. Is held by a roll paper feed member 14 including a pair of rollers 14 a and 14 b having a function of feeding the roll paper 13 and holding the roll paper 13. Reference numeral 15 denotes a cutter member for cutting the roll paper 13 disposed between the roll paper feeding member 14 and the thermal head 4, and the blade edge 15a 'of the movable blade 15a is rotated by rotating the movable blade 15a. Is brought into contact with the fixed blade 15b so that the roll paper 13 is cut.
[0012]
The roll paper 13 fed from the roll paper roll 12 by the roll paper feeding member 14 passes between the movable blade 15a and the fixed blade 15b of the cutter member 15 in an inoperative state, and is inserted between the platen roller 3 and the thermal head 4. After the thermal transfer printing is performed by the ink ribbon 7, the cutter member 15 is operated to cut the roll paper 13 into a predetermined length. The roll paper 13 that has been printed and cut is configured to be carried out of the recording paper discharge port 11 by the recording paper discharge member 10.
[0013]
Reference numeral 16 denotes an original tray. The original placed on the original tray 16 is separated into individual sheets by an original separating roller 17 and then conveyed by an original conveying member 18 including a pair of rollers 18a and 18b. Then, it is configured to be read by the reading sensor 19 and carried out from the document discharge port 20. Reference numeral 21 denotes an operation unit provided with a key 21a and the like.
[0014]
As described above, since both the cut paper cassette 1 and the roll paper roll 12 are installed in the image recording apparatus, the cut paper and the roll paper can be properly used properly, so that the convenience of the image recording apparatus is improved. To do.
[0015]
Further, since the cut paper and roll paper conveyance paths to the thermal head 4 are provided separately, even if a trouble such as a paper jam occurs in one of the paths, the other path can be used.
[0016]
Further, a cutter member 15 for cutting the roll paper 13 is not provided between the roll paper feeding member 14 and the thermal head 4 but on the downstream side of the thermal head 4 (for convenience, the paper conveyance direction is referred to as the downstream side). It is arranged. When the cutter member 15 is disposed on the downstream side of the thermal head 4, printing is completed, and the leading end of the cut roll paper 13 is positioned at the thermal head 4. Then, cut paper cannot be used. Therefore, for example, the roll paper feed member 14 must be reversed to return the cut end of the roll paper 13 to the vicinity of the roll paper feed member 14. As described above, when the cutter member 15 is arranged on the downstream side of the thermal head 4, the roll paper 13 must be reversely moved after printing is completed, and the work time becomes long and the roll paper feed member 14 is There is a problem that it is necessary to provide a mechanism for reverse rotation, and the structure of the image recording apparatus is complicated. In the present invention, since the cutter member 15 for cutting the roll paper 13 is disposed between the roll paper feeding member 14 and the thermal head 4, printing is completed, and the leading end of the cut roll paper 13 is the thermal head. 4, since the cut paper can be used immediately after printing on the roll paper 13 and cutting of the roll paper 13, it is not necessary to provide a mechanism for causing the roll paper 13 to run backward. The recording apparatus can be simplified and downsized.
[0017]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be achieved.
[0018]
Since both the roll paper and the cut paper are provided, the cut paper and the roll paper can be used properly as appropriate, and the convenience of the image recording apparatus is improved.
[0019]
Since the cutter member is placed between the roll paper roll and the thermal head, recording is completed, and the leading end of the cut roll paper does not hit the thermal head, so recording on the roll paper and cutting of the roll paper After that, cut paper can be used immediately, and it is not necessary to provide a mechanism for reversing the roll paper, so that the image recording apparatus can be simplified and miniaturized.
[0020]
Since the cut paper and roll paper conveyance paths to the thermal head are formed separately, even if a trouble such as a paper jam occurs in one of the paths, the other path can be used.
